This study discovers an important cause of dementia in some people

The Alzheimer’s Association estimates that up to 40% of dementias are caused by conditions other than Alzheimer’s disease.

Previous research has shown that as many as 21% of older adults with dementia may be misdiagnosed with Alzheimer’s disease.

A misdiagnosis can result in patients not receiving the appropriate treatment and prevents them from participating in clinical trials that could improve their overall care.

According to the U.S. Centers for Disease Control and Prevention 2.87 million Americans experienced a traumatic brain injury in 2014, with the rates highest for people age 75 or older.

Children age 4 and younger, and adults age 65 and older were most likely to suffer serious brain injuries after a fall.

In a recent study from UCLA and Washington University in St. Louis, researchers found that traumatic brain injury can be a cause of dementia in some older adults.

With the use of MRI scans, it is possible to distinguish between memory loss caused by Alzheimer’s disease and traumatic brain injury.

The finding is important because it could help prevent misdiagnosis of Alzheimer’s disease.

The study is published in the Journal of Alzheimer’s Disease. The lead author is Dr. Somayeh Meysami, a postdoctoral clinical research fellow.

In the study, the team examined 40 UCLA patients with an average age of just under 68, who had suffered a traumatic brain injury and later developed memory problems.

They used MRIs, which can reveal subtle abnormalities in patients with neurological disorders, such as Alzheimer’s.

Using a software program to analyze the MRI scans, the study revealed that TBI caused the most damage to a brain region known as the ventral diencephalon, with the least amount of atrophy occurring in the hippocampus.

The ventral diencephalon is linked to learning and emotions, whereas the hippocampus is involved in memory and emotions.

The hippocampus also is the region of the brain that is most impacted by Alzheimer’s disease.

The team says this study offers further evidence that not all memory loss is caused by Alzheimer’s disease.

It can attribute to traumatic brain injury, as well as other dementias and neurodegenerative disorders.
